Chrysanthemum plant named ‘Coral Yograceland’

ABSTRACT

A distinct cultivar of Chrysanthemum plant named ‘Coral Yograceland’, charcaterized by its uniform and outwardly spreading plant habit; strong and freely branching growth habit; dark green-colored foliage; uniform flowering response and habit; early flowering habit; large anemone-type inflorescences; coral pink-colored ray florets; and good postproduction longevity with plants maintaining good substance and color for about three to four weeks in an interior environment.

Botanical classification/cultivar designation: Chrysanthemum×morifolium cultivar Coral Yograceland.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium and hereinafter referred to by the name ‘Coral Yograceland’.

The new Chrysanthemum is a product of a planned breeding program conducted by the Inventor in Fort Myers, Fla. The objective of the program is to create or discover new potted Chrysanthemum cultivars that are suitable for year-round production with uniform plant growth habit, good vigor and strong branching habit, numerous inflorescences, desirable inflorescence form and floret colors, fast and uniform flowering response, and good postproduction longevity.

The new Chrysanthemum is a naturally-occurring whole plant mutation of the Chrysanthemum cultivar Pink Yograceland, disclosed in U.S. Plant Pat. No. 12,950. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant from within a population of flowering plants of Pink Yograceland in January, 2001, in a controlled environment in Fort Myers, Fla. The selection of this plant was based on its uniform plant growth habit, good vigor and strong branching habit, numerous inflorescences, desirable inflorescence form and floret colors, fast and uniform flowering response, and good postproduction longevity.

Asexual reproduction of the new Chrysanthemum by vegetative tip cuttings was first conducted in Fort Myers, Fla. in April, 2001. Asexual reproduction by cuttings has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Coral Yograceland has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, and/or light level, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Coral Yograceland’. These characteristics in combination distinguish ‘Coral Yograceland’ as a new and distinct Chrysanthemum:

1. Uniform and outwardly spreading plant habit.

2. Strong and freely branching growth habit.

3. Dark green-colored foliage.

4. Uniform flowering response and habit.

5. Early flowering, 8-week response time.

6. Large anemone-type inflorescences.

7. Coral pink-colored ray florets.

8. Good postproduction longevity with plants maintaining good substance and color for about three to four weeks in an interior environment.

Plants of the new Chrysanthemum differ primarily from plants of the cultivar Pink Yograceland primarily in ray floret coloration as plants of the cultivar Pink Yograceland have pink-colored ray florets.

Plants of the new Chrysanthemum differ primarily from plants of the cultivar Honey Yograceland, disclosed in a U.S. Plant patent application No. 10/676,787 filed concurrently, primarily in ray floret coloration as plants of the cultivar Honey Yograceland have light orange bronze-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of the cultivar Apricot Blush, disclosed in U.S. Plant Pat. No. 9,518. In side-by-side comparisons conducted in Fort Myers, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Apricot Blush in the following characteristics:

1. Plants of the new Chrysanthemum were more vigorous than plants of the cultivar Apricot Blush.

2. Plants of the new Chrysanthemum had anemone-type inflorescences whereas plants of the cultivar Apricot Blush had daisy-type inflorescences.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs, following observations and measurements describe plants grown and flowered during the spring in Salinas, Calif., in a fiberglass-covered greenhouse and under conditions which approximate those generally used in commercial potted Chrysanthemum production. During the production of these plants, the following conditions were measured: day temperatures, 21 to 27° C.; night temperatures, 17 to 19° C.; and light levels, 5,000 to 6,000 foot-candles. Four unrooted cuttings were directly stuck in 15-cm containers, exposed to long day/short night conditions, and pinched once about 14 days later. At the time of the pinch, the photoinductive short day/long night treatments were initiated. Plants used for the photographs and description were grown as disbud-types. Measurements and numerical values represent averages of typical flowering plants.
